I do get fed up with people calling us prudish compared to Germans, Scandis, etc. Personally I have no desire whatever to see droopy, flabby bodies, fat wobbly bottoms or sagging old boobs, let alone old men's dangly bits.
On a very crowded beach in Greece I once unwittingly got a far too close-up face-full of some uninhibited old German woman's fanny - not a pretty sight - enough to put me off my lunch, I can tell you.
I don't consider myself remotely prudish generally, , but some things are IMO better covered up.
